The purpose of this report is to record an epidemic of streptococcus septicemia occurring late in November and early in December, 1921, in a ward of seventeen babies in a nursery home.

The age of these infants ranged from one month to 7½ months. They were housed in a new building in a commodious ward, well ventilated and well lighted, with a sun porch attached, where they spent the day in individual cribs and were returned to their beds in the ward at night.

Before the onset of the epidemic all the babies were in good general condition, gaining in weight and having no gastro-intestinal disturbance. All were bottle fed babies, on whole milk dilutions with water and sugar added. Two were receiving small amounts of breast milk in addition to their cow's milk formulas. The milk and water used was boiled three minutes.
